1 Introduction
1.1 Overview
The programmable wall stations of the modular PWS system (Programmable Wall Station) allow local
control and operation of various devices and systems via CAN-Bus. A programmable wall station lets you
control several funct ions, f or exampl e: sour ce sele ction, volume con trol, muting or powerin g on/off devices.
In addition, using a suitable central control unit allows controlling a variety of facilities in a building (light,
heating/air condition, etc.).
The minimum configuration for the operation of a programmable wall station consists of:
• A front unit (e.g. PWS-4)
• A CAN coupler (PWS-C)
• A software configuration created in IRIS-Net™ and transferred to the programmable wall station via
CAN-Bus
• A CAN-Bus master unit to be controlled (e.g. Electro-Voice NetMax N8000)
The front units represent the part of the programmable wall station for the user to access, i.e. the user
interface. Different front units with differing numbers and types of controls or indicators are available. A
number of front units grouped in a single programmable wall station have to be connected in series, with
up to three front units connected to a single bus coupler.
The CAN-Bus coupler PWS-C provides connectio n between front units and the CAN-Bus. T he maximum
number of units connected to a CAN-Bus (e.g. PWS-C, Remote Amplifier, etc.) depends on employed
central control unit. Please consult the corresponding manuals.

1.2 Applications
PWS panels can be included in any audio installation, for example:
• Stadiums and theaters
• Cruise ships
• Multi-purpose halls
• Schools and Universities
• Government agencies
• Airports
• Theme parks
• Exhibition centers and museums
• Conference centers and hotels
1.3 IRIS-Net™
When shipped, programmable wall stations have not been configured yet. The progr amming of control and
indication functions is done using the PC software IRIS-Net™ (Intelligent Remote & Integrated
Supervision). After transferring the custom configuration to the programmable wall station, the PWS
becomes functional and it is able to control the system components (N8000, remote control amplifiers,
etc.) independent of a PC or IRIS-Net™. Simultaneous Control from a PWS and IRIS-Net™ is possible.
The IRIS-Net™ help files contain all the information on configuration, operation and monitoring of all
programmable wall station functions. The following illustration shows an example of a PWS system in
IRIS-Net™.

2 CAN-Bus coupler PWS-C
The CAN-Bus coupler PWS-C provides connection between front units (e.g. PWS-4) and the CAN-Bus.
The CAN-Bus coupler registers the activation of controls on the connected front units and sends the
needed information via CAN-Bus to the devices to be controlled, but also directs info rmatio n received from
the CAN-Bus to the control units for indication. The CAN-Bus coupler offers connectors for CAN-Bus and
power supply as well as DIP switches for the CAN-Bus configuration (baud rate, bus termination and CANBus address). The CAN-Bus coupler PWS-C is suitable for European and US-type flush-mount boxes.

3 PWS Front Unit PWS-4/PWS-6
PWS-4 and PWS-6 are front units of the modular PWS system. They are meant for installation in a UStype wall box. Typical applications are: source selection, volume control and preset-switching.
All controls and indicators of the front units are freely configurable via IRIS-Net™. Individually labeling the
controls and indicators according to their assign functions is possible after removing the label field cover.
The front units PWS-4 or PWS-6 are being used in combination with the CAN-Bus coupler PWS-C. Up to
three front units can be operated on a single PWS-C.
3.1 PWS-4
The PWS-4 has in total 6 buttons, with the upper four buttons having a separate Status-LED, each. The
two lower buttons can be used as Up/Down buttons. The set parameter status is signaled via LED-chain.

Only the supplied connection cables should be used for proper operation. The following illustration shows
the connection of two front units of a programmable wall station.
Other than connections, no physical configuration of the front units is required, as the assignment of

Mounting a Programmable wall station in a US Single Gang Wall Box
For mounting a programmable wall station you have to lock the PWS- C and a front un it of a pr ogrammabl e
wall station together using two screws. Using the supplied connection cables, connect additional front
units. Please also refer to this manual’s corresponding chapters describing the connection procedure for
the front units being used.
4.1 Hardware Configuration
The DIP-switches of the PWS-C allow setting the baud rate (page 11), termination (page 13), and CANaddress (page 14). An overview of default DIP-switch settings is provided on page 6.
Baud Rate
Determination of a suitable baud rate
The maximum allowable baud rate of the CAN-Bus is indirect proportion to the bus length. For smaller
networks, baud rates of up to 500 kbit/s are possible. Large networks require a lower baud rate (down to
the minimum baud rate of 10 kbit/s). The follow ing table illustrates the relationship between baud rate and
bus length, i.e. network dimensions. Generally, bus lengths over 1000 meters should always employ CANrepeaters.
CAUTION:
All devices on the CAN-Bus have to be set to the same baud rate.

NO PWS-C IS USED
PROGRAMMABLE WALL STATION
12 Owner’s manual
Setting the Baud Rate
Setting the bus coupler’s baud rate is possible by using switches 1, 2
and 3 of the TERM/BAUD DIP-switches. Potential baud rates and
corresponding switch settings a re shown in the following table. Only
when set to PROG Mode, it is possible to change the programmable
wall station’s baud rate via IRIS-Net™. With all other switch settings,
the previously selected value for the baud rate is maintained.
A dark shaded field in the table marks the default value when shipped. In PROG mode, the default data
rate is 10 kbit/s.

PROGRAMMABLE WALL STATION
Owner’s manual 13
Setting a default baud rate in PROG mode
As shown in the above table, setting a fixed baud rate is possib le when conn ecting a PWS- C to an al rea dy
existing CAN-Bus. When connecting a PWS-C in PROG mode, setting the baud rate directly on the PWSC is possible by following these instructions:
1. Activate the power supply of the PWS-C
2. Set the desired baud rate using the DIP-switch TERM/BAUD (see page 12)
3. Wait until the new baud rate is adopted, which is signaled by a dimmed CAN-Status-LED.
4. PROG mode settings with DIP-switch TERM/BAUD (see page 12)
The PWS-C can now be taken into operation with the baud rate set under step 2.
Termination
Both ends of a CAN-Bus have to be terminated using a 120 Ω
terminator. Missing or erroneous termination can result in
malfunction. Contact 4 of DIP-switch 1 allows activating the PWS-C’s
integrated terminator (see the following table).
A dark shaded field in the table marks the default setting when
shipped.
The following illustration provides an example of a NetMax-Systems, with Remote Power Amps and
programmable wall station being connected via CAN-Bus. Both ends of the CAN-Bus are terminated using
terminators.
NOTE:
The CAN-Status-LED light for 3 seconds whenever changes are applied to the DIP-switches with
the power supply being activated. The new setting is adopted only when the CAN-Status-LED is
dimmed.

14 Owner’s manual
CAN address
Every programmable wall station has to have a unique CAN address
to be identified on the CAN-Bus. The usable address range is: 1 (01
hex) up to 250 (FA hex). The PWS-C’s ADDRESS DIP switch (see
page 6) allows specifying the CAN address by setting a two-digit
hexadecimal number. A table of possible CAN addresses and
corresponding DIP-switch settings is provided on page 45.
The default CAN address when shipped is 0 (00 hex).
CAUTION:
T o prevent network fault s, each CAN address may exist once only throughout a system.
Conflicts on the network would be the result.
NOTES:
Various programmable wall stations of a system can be easily configured when their
CAN addresses are in consecutive order.
A programmable wall station is disconnected from the CAN-Bus when its CAN address
has been set to 0.
If the setting of the DIP-switch is changed, the CAN status LED lights up for 3 seconds.
The new setting becomes effective when the CAN status LED is dimmed.

4.2 CAN-Status-LED
The entries in following table are arranged after falling priority, i.e. if two conditions arise at the same time,
only the upper condition in the table is indicated.
4.3 Connection
The PWS-C has a 10-pole terminal clip for the connection of CAN-Bus
signal transmission and power supply. Using cable with diameters
between 0.5 mm and 0.8 mm (20 -24 AWG) is possible. For further
